Embodiment Construction

[0023] figure 1 An elevator installation 1 is shown with at least one elevator car frame 2 , which can be traveled in a travel space 3 provided for the travel of the elevator car frame 2 . For example, the travel space 3 can be arranged in an elevator shaft of a building. Here, a plurality of floors 4 , 5 can be provided in the building, which floors 4 , 5 represent the stops 4 , 5 . Floors 4, 5 are shown here by way of example, in practice significantly more floors or stops can be provided.

[0024] The elevator car frame 2 has longitudinal beams 6 , 7 which are connected to each other by cross beams 8 , 9 , 10 . Rollers 11 , 12 are provided on the beam 10 for guiding the traction mechanism 13 . The traction mechanism 13 also runs around a drive pulley 14 of a drive mechanical unit 15 . Depending on the momentary direction of rotation of the drive pulley 14 driven by the drive mechanical unit 15 , the elevator car frame 2 travels through the travel space 3 in an upward di...

Abstract

The invention relates to an elevator system (1) comprising at least one elevator car support (2), which can be moved in a travel space (3) provided for travel of the elevator car support (2), a first elevator car (20), which is arranged on the elevator car support (2), a second elevator car (21), which is arranged on the elevator car support (2), and at least one adjusting device (34), which is used to adjust the first and second elevator cars (20, 21) relative to the elevator car support (2). For this purpose, the adjusting device (34) comprises at least one first gear rack (60.1), which is connected at least indirectly to the first elevator car (20), at least one second gear rack (61.1), which is connected at least indirectly to the second elevator car (21), and at least one gear wheel (29), which engages with the first and second gear racks (60.1, 61.1). The first and second gear racks (60.1, 61.1) are arranged with respect to the gear wheel (29) such that a rotation of the gear wheel (29) causes the first and second elevator cars (20, 21) to move in opposite directions (33, 36; 34, 35).

Description

technical field [0001] The invention relates to an elevator installation with at least one elevator car frame, which can accommodate two or three elevator cars. The invention relates in particular to the field of elevator installations designed as so-called double-deck elevator installations. Background technique [0002] EP1074503A2 discloses a double-deck elevator. In this known elevator, a first elevator car and a second elevator car are arranged vertically one above the other. Furthermore, a spindle drive is provided which serves to operate the two elevator cars. In operation, the two elevator cars either travel toward each other or move away from each other. [0003] A disadvantage of the double-deck elevator known from EP 1074503 A2 is that the spindle drive has relatively high friction, which results in unfavorable efficiency for the adjustment of the two elevator cars. In particular, this entails that the drive must be designed with correspondingly larger dimensi...
